  • the function of polymeric dispersant in such dispersions is manifold. Mainly, they act as stabilizers for the solid fine particulate materials, i.e. the dispersant separates the particles of the solid fine particulate material and thus prevent them from coagulation or clumping and settling from the liquid phase.
  • ком ⁇ онентs may also improve the gloss of the dispersion or enhance its rheology.
  • the dispersing agent e.g. water, organic solvents or mixtures thereof, polymers of variable structure are chosen.
